IMPROVEMENT IN WHIFFLE-TREE ATTACHMENT.

The Schedule refafred 'co in these Lettere 'Patent and making part of the same.

aww- To all, whom it ma/y conce/rn l Be it known that I, LEONARD MANCY, of the town of St. Morgan, in the county of Madison, and State of Illinois, have made'certainnew and useful Improvements in Whiiiie-Tree Attachments; and I do hereby declare that the following is a full and clear description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my invention is in connecting a singletree with levers, in such wise that the draught of a single horse shall counterbalance the action of-draught of two ormore horses upon the'double lor triple-tree attachments, whilst the draught .of all animals is utilized for propulsion.

To enable those skilled'herein to make and use my said invent-ion, I will now fully describe the same, referring herein to the accompanying drawings, of which- Figure l is a plan, and

Figure 2 is a rear-end elevation.- A represents the tongue or shaft of a wagon or other vehicle, such as a gang-plow or harvester, said tongue being attached in the usual manner to the vehicle.

To said tongue I attach, by the pivot-bolt bthe single-tree lever B.

This has, near its outer end, the staple-bolt e, for the single-tree C. f

I arrange, in the end of said lever B, a series of holes, cl c2 ci, into which said staple-bolts c may be put, in accordance with the strength of the animal and other conditions of draught.

I further arrange, in connection with said lever B,

the connecting or link-bar D, which hinges to B by the1 `bolt d, there being in B, again, a series of holes, d d2,

&c., into each of which the bolt d may be entered, in accordance with the conditionsv of draught.

Said link D connects, by the bolt e, with the lever E. This lever has its fulcrum, F, on a block, j', which is iirmly secured, by means of bolts, to the tongue A.

At the other end of the lever E is the staple-bolt g, for connecting the double-tree Gin the usual manner. -A series of holes, g g2, &c., in theA end o f said lever E, permits a change of the point of attachment of the double-tree G.

The actionof the said 'parts is now as follows:

mitted in increased power upon the end of the level' E, but the double-tree attachment G, for two horses, acts upon said lever, as before stated; hence, owing to the apportionment of arm-lengths of said lever, the draught of one draught animal at C is balanced against the draughtof the double team at G. Thus the entire draught-force acts equally to propel the vehicle.

Of course the action of the'levers here described is merely intended to'keep the single-tree C in its proper position with respect to the double-tree attachment G,

-thercby enabling al1 the. draught-animals to-proceed-in line, and equalizing the otherwise disproportionate effects arising from the position of a double team gg one side against a'single animal on the other side ofthel tongue.

Now, as the power of draught varies with the animal, it will be seen that by changing the points of attachment of the staple-boltsc, and thus changing the leverage of the single-tree C, or by changing the staple-bolt attachment g, andthereby changing the lever- 'age of the double team, and lastly, by changing the point oi connection of the link D with the level' C, such variation in the action of the draught-forces may be made as will accommodate thevarious muscular powers of the draught-animals.

Having thus fully described my said invention,

What I claim, is-

l. The combination of the single-tree C, the adjustable staple-bolt c, the lever B, adjustable bolt al, and link D, the leirer E, adjustable staple-bolt g, and doubletree G, substantially as set forth.

2. The v )ivot F on the fulerum-block f, attached at the side o thc tongue A, substantially as set forth.
